It would really depend on why you are selling your 126. If you needed the money, then sell and not even consider a trade with any vehicle unless that "other vehicle" is easier to sell.

If you're selling the 126 but do plan to replace it with an older classic, (regardless of the speed factor and not compare it with your experience with the 126) the Ponton "may' be a good candidate. (but the r=thought of straight swap would only be logical depending on the condition of the Ponton)

At first glimpse the pontons condition seems quite good. The car seems 100% complete, it runs and there aren't any obvious signs of rust. It actualy looks very presentable. I need to do a personal inspection.

I don't need the money but with my interest in switching cars from time to time the ponton seems like it would be more saleable. Plus I have always loved these and to own one would be great.
